Exploitation evidence

Disclosed: evidence found.
CVE published 31 Aug 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 5 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Red Hat has released an official security update that fixes the privilege escalation vulnerability. Users should apply the provided iscsi-initiator-utils package update for Red Hat Enterprise Linux 10.0 Extended Update Support and related variants as soon as possible. Refer to Red Hat's official update instructions at https://access.redhat.com/articles/11258 for detailed remediation steps. No additional mitigation actions are indicated beyond applying the update.

Description

A privilege escalation vulnerability (CVE-2026-44943) exists in the open-iscsi component of the iscsi-initiator-utils package used in Red Hat Enterprise Linux 10.0. This flaw involves a path traversal issue that could allow an attacker to escalate privileges. Red Hat has issued an important security update to address this vulnerability along with bug fixes and enhancements. The update is available for multiple architectures including x86_64, s390x, ppc64le, and aarch64. Users of affected Red Hat Enterprise Linux versions are advised to apply the update to mitigate the risk.

Impact

Successful exploitation of CVE-2026-44943 could allow an attacker to escalate privileges on affected systems, potentially gaining unauthorized elevated access. This could compromise system integrity and security. The vulnerability is rated as high severity by the source data, indicating significant risk if unpatched.

Summary

The iscsi-initiator-utils packages provide the server daemon and utilities for managing the iSCSI protocol, which facilitates distributed disk access over IP networks. A security flaw identified as CVE-2026-44943 in the open-iscsi component allows privilege escalation through a path traversal vulnerability. Red Hat has released an update for Red Hat Enterprise Linux 10.0 Extended Update Support and other supported variants to fix this issue. The advisory also includes bug fixes and enhancements unrelated to the security flaw. The update is rated as important by Red Hat Product Security.

CWE-22Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
